3D Stacked Memory Developed to Aid Graphics Processing

Researchers at the Pacific Northwest National Laboratory and University of Houston have developed a means to increase 3D rendering speeds by up to 65%. It involves leveraging the logic layer that exists within 3D stacked memory to do some processing within the memory, instead of putting it on the GPU.

The PNNL researchers normally work with supercomputers, but when one of them asked if 3D stacked memory could be used to help render 3D graphics, the attention shifted towards video games. Science will still benefit from this work though, as 3D rendering is used with visualizations, models, and virtual reality. During their testing on Doom 3 and Half-life 2, the researchers found the best step to have the memory process is one of the last steps, anisotropic filtering as it often creates a lot of traffic on the graphics card. By removing this traffic and performing the filtering as the first step, they found the greatest performance boost.
